Specification of Letters-Patent t n J 1922 Application filed April 27,1918. Serial No. 231,163.

with a suspending device for holding the object to be treated in themetallic bath while it is being subjected to the electrolytic action,the said device being in the form of a clamp consisting of a pluralityof metallic plates between which the object to be treated can bedirectly supported and connected with the negative pole of the batteryforming the cathode, the silver, nickel, copper etc., being suspended inany suitable well known manner and connected with the positive pole ofthe battery, (the anode), the object of the present invention residingin the con-' struction'of a clamp in which the electrolytic action canbe accomplished by direct conduction and with an elimination of unduetime and labor and also with an appreciable saving of materials.

With the above and other objects in view which will appear as the natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangements of parts which will hereinaifter befully described and particularly pointed out in the claim.

In the accompanying drawings, has been illustrated, several preferredforms of the invention, it being, however, understood that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and modificationswithin the scope of the claim may be resorted to when desired.

Figure 1 is a front view of my improved suspending device and clamp.

Figure 2 is a section therethrough taken on the line 2-2 of Figure 1with parts in full lines.

Figures 3 and 4 are views similar to Figure 2 showing slightmodifications of the invention;

The invention comprises a suitable supporting hook 5 adapted to besuspended from the usual supporting wire, not shown, which is arrangedin. the customary manner above the metallic bath and as illustrated saidhook is provided with a suitable handvhold 6. by means of which same canhe quickly applied to or removed from the wire as the occasionnecessitates. The said hook is provided with. a shank 7 to which therelatively attenuated branches8 of copper or metallic clamping jaws 9are secured.

The said branches 8 may be detachably connected with the shank 7 byproviding bolts 10 which are designed. to be passed through the shank .7and associated withthe branches 8 of the clamping jaws a'shereinillustrated. By interposing the shank 7 be tween the branches 8 of thementioned clamping jaws the latter are capable of being moved oradjusted with relation to one another in order that the work or articleto c be electro-plated can befirmly confined between said jaws. Thesejaws are provided with relatively long heads 11, which are adapted tocome in fiat and continuous contact with the sides of said object to) betreated. In this manner and through the fact that the hook is connectedwith the negative pole of the battery circuit a good electricalconnection is established between the clamp and said plate or article tobe electroplated.

I do not wish to limit myself to any precise mode of adjusting the jaws9 into clamping relation to one another but for conventionalillustration will make use of bolts 12,

the same being extended through the heads 11 as shown in Figures 1 and 2whereby said heads may be brought into firm gripping contact with thesides of the plate or article to be electro-plated. Many obvious andwell known devices can be employed lfor efiecting such relativeadjustment of the mating jaws 99 as will be understood.

In Figure 3 the shank 18 is provided with a continuous jaw portion 14,while riveted at 15 to the shank is a mating adjustable jaw 16, the samebeing constructed of hard drawn copper. FiXedly supported from themovable jaw 16 is a stud 17 which pames through the jaw 14 and at oneside of the latter and supported for swinging movement from the stud isan eccentric clamp 18 which, when adjusted to one position, will causethe two jaws 14 and 16 to be advanced toward one another. When theeccentric is adjusted to another position the jaws are free forseparation. I prdfer to provide for an automatic separation of therespective jaws and find it desirable to rivet a spring 19 to the jaw 16and extend the free end of the spring against the jaw 14 as hereinillustrated.

In the form of the invention shown in Figure 4, the shank 20 is providedwith an integral jaw 21 which is pivoted at 22. to a movable jaw 23.Said movable jaw is provided with a tail extension 24 and interposedbetween the shank 20 and said tail is a spring 25. In this manner theefi'ective gripping ends 26 of the respective jaws are normally advancedinto gripping relation with one another. The tail 24 isprefferably'curved at 27 in order that the thumb of the oper ator can bereadily placed thereagainst and sufficient pressure applied to permit ofa relative separation of the effective gripping ends 26. r

Inthis manner of suspending the article to be treated the electrolyticaction will arise by direct contact with the object to be treated;considerable time and labor can be eliminated and an appreciable savingof materials effected.

Each of the devices herein illustrated has its jaws provided withgripping spurs 28 adapted to engage with the work.

What I claim as new is:

A device of the class described comprising a semi-circular supportinghook provided with a shank having spaced openings therein, a T-shapedhandle extending from said hook, a pair olf elongated horizontalclamping members disposed in a plane at right angles to said hook andhaving spaced aligned openings formed therein, parallel attachingmembers extending at right angles from one edge of said clamping membersand provided with spaced openings in alignment with the openings in saidshank, a plurality of bolts passing through the openings aforesaid and aplurality of nuts engaging said bolts.

In testimony whereof I aifix my si nature.
